Virtual interactive experiments (vexp) is a framework to promote the development and use of
cooperative e-learning experiments over the internet. Interactive scientific experiments which can be controlled
by various users synchronously. With virtual experiments scientists and students can investigate behaviors of
complex processes, which are hidden or difficult to observe in real world observations. Students can build virtual
collaborations - so called learning-groups - with other students, experts or tutors, which are working interactively
on the same experiment. Every member in a learning group can observe instantaneously activities of other members.
